FLAME REGULATOR AND EXTINGUISHER FOR LAMP-BURNERS.

SPECIFICATION forming part of Letters Patent No. 354,268, dated December14, 1886.

Application filed January 9, 1886.

To aZZ whom it may concern.-

Be it known that we, CHARLES W. STIFF and JosEPH IVArRoUs, citizens ofthe United States, residing at Foxborough, in the county of Norfolk andState of Massachusetts, haveiir vented certain new and usefulImprovements in Burners for Lamps and the Like, and Flame Regulators andExtinguishers for Use in Gonnection Therewith; and we do hereby declareto the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to burners for lamps I 5 and the like, and toflame regulators and extinguishers for use in connection therewith,

. and has for its object to provide aconstruction which will permit thewick to be folded over the tube so as to form a folded or rounded edgeto be lightcd,instead ofa cut edge,as heretofore,

whereby is obtained a more uniform and even flame, andihe exposed edgewill burn and last longer than when a cut edge is used.

It has also for its object to provide means for regulating the size ofthe flame, and extinguishing thesame when desi red; and to such ends theinventionconsists in the construction, and also in the combination ofparts herei11- after particularly described,and then sought to 50 bespecifically defined by the claims.

Figurel is a side elevation of a portion of an 0ilstove with our burnerapplied, parts-being broken away. Fig. 2 isa-crosssection on line or wof Fig. 1.

In the following description the invention will be described as appliedto an oil-stow burner; but it will be understood that it may be appliedto lamps and other kinds of oilburners, so as to operate in the samemanner.

In the drawings, the letter A designates the ordinary wick-tube ofanoil'stove detached from the stove, and B the wick which passes throughthe same from the oil-reservoir, the wick being raised by a toothedwheel, 0, and shaft D, as usual.

The letter E designates a slide, clasp, or c0llar designed to fit downover the wick-tube, and is preferably formed with inwardly-projectinglips F at both ends, so as to extend over the wick and thus insure thewick being Serial No. l88,050. (No model.)

the sameheight at both ends. Ihcselips,however, may be omitted. In usingthis slide the wick is raised and its end a turned down or foldedalongside the tube, and the slide fitted down over the tube andturneddown portion of the wick, so as to hold the folded portion of thewick in place. This forms a folded or rounded edge, I), to be lighted.This edge is uniform and firm, and gives a regular flame, and burnslonger than when a selvage edge is exposed. \Vhen the edge becomes somuch burned thatit cannot be longer used, the slide tion carried fartherdown,and, when necessary, trimmed off and the slide again applied. Thewick-tube is set at such a height that the flame will be at its highestpoint with the tube so set. In order to regulatethis flame a shield orcap, G, is applied or attached to the slide and actuated by a lever, soas to be adjusted more or less over the wick, and thus regulate the sizeof the flame. The farther the cap is advanced In the form illustratedthe cap is journaled on pins c'to the end of the slide, and is soweighted or balanced that normally it will fall or drop backward, sothat a support must be afforded forit. This cap is raised and supportedby means of a lever adapted to bear against it and press it upward. Asuitable lever is composed of a sliding arm, I, formed with aslot, d,and secured to the slide E by headed pins 0, which also serve as guidesfor the arm in its movement. To the inner end of this arm is pivoted anarm, J, formed with a curved slot, f, and having a finger, g, projectingfrom its free end,which is adapted to bear against the lower part of thehinged cap. A headed pin, h, passes through the slots f d, and serves todeflect the arm J upward and downward in the back-andforth movement ofthe arm I. In the upward movement of the arm J it strikes the cap G andthrows it over the wick proportionately to the movement of the arm, andto that extent reduces the size of the flame. The cap is held at itsadjusted position by the arms I and J, the weight of the cap not 'beingsuflicient to overcome the friction be tween the parts which holds thearm J in its raised position. The cap can by the movement over the wickthe smaller the flame is made.

is removed,the wick raised,and the bu rued porof the lever, composed ofthe two arms, be thrown far enough over the wick to extinguish the flameentirely. A lip, i,on the cap strikes against the edge of the slide soas to prevent the cap from going too far over. When the arm Jis drawndown, the cap falls back by its own weight. It will thus be seen thatthe size of the flame is regulated and also extinguished by the samecap.

The parts are simple in construction, effective in operation, cheap toproduce, not liable to get out of order, and may be made of varioussizes,and may-be altered in some details of construction withoutdeparting from the spirit of our invention.

Having described our invention and set forth its merits, what we claimis- 1. In an oil-burner, the combination therewith of a wick-tube, awickfitted therein and folded over the upper end of the tube onto theoutside thereof, and a clasp fitted over the tube and outside portion ofthe folded wick, substantially as described.

2. The combination,with an oil-burner, of a wick-tube, and a claspfitted over the tube at its upper end to hold aturned-down end of a wickagainst the tube,the said clasp being of a greater diameter than thetube to leave a space between the clasp and tube to receive theturned-down portion of a wick, substantially as described.

3. In an oil-burner, the combination,with a wick-tube, of a slide fittedover the tube and provided with inwardly-turned lips at the endsthereof, said slide being of greater diameter than the tube to permit awick to be passed between it and the side of the tube, substantially asdescribed.

4. The combination of a slide to fit over a wick-tubc,an adjustable caphinged to the slide, a slotted sliding arm, pins connected to the slidefor guiding the arm along the slide, and asecondary arm pivoted to themain arm and formed with a curved slot, through which apin connectedtothe slide pas es and guides the arm, substantially as described.

In testimony whereof We aifix our signatures in presence of twowitnesses.
